ACOUSTIC SOURCE TRACKING AND SELECTION
First Claim
1. A system for processing at least one signal acquired using one or more acoustic sensors, the at least one signal having contributions from one or more acoustic sources, the system comprising:
- a memory configured to store computer executable instructions; and
a processor communicatively connected to or comprising the memory and configured, when executing the instructions, to;
obtain sensor data from one or more sensors other than the one or more acoustic sensors; and
use the sensor data in executing an acoustic source separation algorithm on the at least one acquired signal to separate from the at least one acquired signal one or more contributions from a predetermined acoustic source of the one or more acoustic sources.

Abstract
The present disclosure relates generally to improving acoustic source tracking and selection and, more particularly, to techniques for acoustic source tracking and selection using motion or position information. Embodiments of the present disclosure include systems designed to select and track acoustic sources. In one embodiment, the system may be realized as an integrated circuit including a microphone array, motion sensing circuitry, position sensing circuitry, analog-to-digital converter (ADC) circuitry configured to convert analog audio signals from the microphone array into digital audio signals for further processing, and a digital signal processor (DSP) or other circuitry for processing the digital audio signals based on motion data and other sensor data. Sensor data may be correlated to the analog or digital audio signals to improve source separation or other audio processing.
